Perhaps you should try some spelling variations:
"diplomat" » "diploma", "diplomatic", "diplomatie"
"diplomats" » "diplomas", "diplomatics", "diplomaties", "diplomatic", "diplomacy"
"diplomatics" » "diplomaics", "diplomaticics", "diplomatieics", "diplomatic", "diplomatie", "diplomatique"
"diplomatische" » "diplomaische", "diplomaticische", "diplomatieische", "diplomatischen", "diplomatic", "diplomatie"
"diplomacyic" » "diplomacy", "diplomatic", "diplomacia"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ("diplomat" OR (("diplomats" OR ("diplomatics" OR "diplomatische")) OR "diplomacyic")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(\"diplomat\" or ((\"diplomats\" or (\"diplomatics\" OR \"diplomatische\")) or \"diplomacyic\"))".
• Removing quotes may allow a broader search: ( diplomat or (( diplomats or ( diplomatics OR diplomatische )) or diplomacyic )).
• Adding a wildcard symbol may retrieve word variants: ("diplomat" or (("diplomats" or ("diplomatics" OR "diplomatische")) or "diplomacyic"))*.
